Just a quick mashup of random unused parts. Basicly it's a 1/2 QEV piloted with a 1/4 blowgun, chamber is 22mm copper and the barrel is 6mm alluminium sleeved inside 15mm copper piping The shot done was at around 100 psi and i have yet to crank up the pressure.

Unfortunatly there is only a video because photobucket dosen't accept pictures from my camcorder.

The pellets are modified slightly so that the fit the 6mm barrel perfectly.Velocity? i don't realy know but i'm guessing somewhere in the high 400s low 500s.

Hmmm, 300psi anyone?

Your 0.12g BBs have a horrible ballistic coefficient compared to heavy pellets, so really what you're seeing is that your pellets *slow down* much quicker than the BBs. If you can see the pellet, it's clearly not moving that fast anyway
